NSHEV Roof Louvres at work: The Wharf, Droylsden Marina
Project
D+H UK supplied and installed a mechanical smoke ventilation solution in a Watkin Jones Homes development. The Wharf, set alongside Droylsden Marina offers a collection of modern 1, 2 and 3 bedroom apartments.
System
The apartment block has 6 levels connected by a central staircase. EN certified dampers are fitted to each floor along with local smoke detection. The fans are located within the smoke shaft with a roof louvre situated above them, providing weather protection.
Products
If smoke is detected in the building the system will open the corridor AOV, smoke shaft damper, head of stair vent and roof louvre. The duty fan will run to extract any smoke located in the corridor. In the event of a power failure the standby fan will engage.
